Ford 3.3 hybrid specs: 204 ci (3.3L) 6-cylinder, 3.559 x 3.413 in (90.4 x 86.7 mm) bore and stroke. Rated 318 hp, 2020–2026. Used in the Ford Explorer. DOHC.
The Ford 3.3 hybrid is close to square: 3.5594" bore against 3.4134" stroke, within 4.3%, which splits the difference between a high-revving layout and a torque layout. The 3.4134" stroke does not reach 4,000 ft/min of mean piston speed until about 7,050 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 6 cylinders displaces 34.0 ci (557 cc).
It is one of 4 engines in the Cyclone V6 family, all of them 204 ci — the differences between them are in compression, heads and rating, not displacement. 7 factory variants share these dimensions, rated at 318 hp across 2020–2026.
